Abstract

An experiment was conducted during 1997 and 1998 to study the response of groundnut to lime and nitrogen. The results revealed that highest N, P and K uptake both in Kernel and stover and total uptake were recorded under 50% lime requirement (50% LR). Available N, P2O5, and K2O recorded after harvest of the crop were significantly higher under 50% LR than that of unlimed condition. Application of nitrogen resulted in significantly higher N, P and K uptake but 40 kg N/ha application caused maximum increase. Nitrogen levels recorded significantly higher available N in soil after harvest over no nitrogen.
